Specification of Letters Patent.

Serial No. 611,515.

the steam or air, are injected or forced through nozzles into the mixing chamber; and a inain object thereof is to provide an ellicient device for regulating the `tlow of steam from the steam discharge nozzle, so that the steam or air will be sprayed and become intimately associated in the proper proportions with the liquid fuel forced through the fuel discharge port.

A further object is to provide a burner construction in which the atoniized fuel discliarged in a circular forni, thereby permitting a central placement of the burner in the fire box, so that all portions thereof are heated to a uniform temperature.

I accomplish the above objects by ineans of the device described herein and shown in the accompanying drawings, in which Figure l- .is a central vertical section through iny complete burner. Fig. Q 'is a front elevation of the steam regulating device. Fig. Sw is a partial central section taken on line 33 of llig. .'l. Fig. etis a vtransverse section taken on line L,1f-1t of Fig. l. Fig. 5 is a perspective view of the steam nozzle closure.

ln the drawings, l0 designates a lower litting provided with a vertically disposed bore ll, and transverse bores 112 and 13 disposed one above another. Bore 1l is provided at the lower end thereof with a cleaning plug la, its upper end being threaded for the reception of the lower threaded end of a vertically disposed steam-way rlhe upper end of the steam-way is in screwthreaded engagement with the 'lower end of the steam nozzle base 1G, the nozzle 17 being detachably secured to the upper end thereof. This nozzle is preferably cone-shaped and is provided with an oriilice 1S through which the steam is injected into the mixing' chamber 19, as will be more clearly described hereinafter.

The upper end of bore l1 is enlarged and threaded for the reception of the lower threaded end of an oil-way Qt) that extends upwardly and surrounds the steam\\'ay. (')il-way Q() is in screw-lhreaded engagement with the lower end of an extension :sleeve or 4cap 2l, and a. burner hood Q- is secured to the upper end thereof. lhis hood is prefer ably cone-shaped, terminating Ain a cupshaped chaulber 2?) that forms with the inverted cup-shaped plate 2l; the mixing chamber 1f) of the burner. llood 22 is also provided with a centrally disposed orilice or oil port Q5 through which the .liquid fuel is adapted to be injected into the mixing chamber.

Slidably mounted in nozzle Ilt') is a ralve stopper 2G which is clearly shown in Figs. 1I. and 5 of the drawing. '.lhis stopper preferably consists of a tube having the lower portions eut away to form oppositely disposed bearingl arms 2T adapted to pass through apertures il?, formed in the head r.) of a cap stud tit). The outer end of this stud is reduced in diameter, so as to form a shoulder l. and is provided with a spacing sleeve $32, a nut 33 engaging the outer end thereof and maintaining the inverted cup-shapial plate Q-'t in rigid engagement therewith. lt will be observed by an inspection ot the drawing, and particularly Fig. il, that the diameter of stopper t is exactly the same as the diameter ofthe orifice lti in the steam nozzle, thus enabling the operator to completely shut olli' the passage ol.' steam through the orit'ice. livotally secured by means of a pin 35 to the lower end of bearing arms 27 of stopper 2G is a valve rod t' which extends downwardly, and is provided on its lower end with a transverse aperture Pfl which is adapted to be engaged by a pin 3S mounted in the end ot. an eccentric rod 39, which extends through 'transverse bore 13. This rod is provided on lthe end that passes through the bore l?) with a cylindrical bearing head .10 and an annular shoulder ell, being held in stezunwtight engagprement with the bore 1,3 by a stalling box la formed by a packing nut 13.

Fitting l() is provided with an extension fill, a longitudinal bore Lt5 extending therethrough and comuiunicating at its upper end with the oil-way Q0, as clearly shown in Fig. of the drawing, this bore con'unnni- Cates with an oil pipe to which is provided with a suitable valve (not shown) for controlling the passage of liquid fuel therethrough, it being understood that the oil is injected or forced through this pipe into the burner. rilransverse bore 12 communicates ivith a steam pipe 1LT that extends at right angles to the fitting 10, and is in screwthreaded engagement with a steam-fitting 1S provided with a steam-inlet 49. rihe outer end of fitting 4S is also provided with a bearing in which is rotatively mounted the outer end ot eccentric rod 39, a handle 51 being provided for its rotation. A pivoted segment or locking arm 52 is mounted on iitting t8 and is adapted to engage the outer tace of handle 51 contacting with the edge oit a lug thereon, an eccentrically mounted latch serving to rigidly maintain and lock the rod in the desired position.

rlhe operation of my improved burner is as tollovvs: Steam and oil are admitted simultaneously through the oil and steam pipes et@ and 4J?, respectively, into iitting l0, the eccentric rod being rotated to bring the valve stopper 26 into the proper regulated position. The steam passes through the nozzle 18 in a thin circular sheet drawing a suihcient supply et oil through orifice rlhe fuel outlet nozzle is of a capacity that will pass the maximum amount of oil that the steam nozzle Will draw. rlhe atomized steam and oil pass upwardly into the mixing chamber Where more or less rotary movement is caused by the curved cross section of the chamber. After being thoroughly mixed the t'uel is forced out through the annular opening 55 in the form of a thin flat sheet.

it Will be observed that by forming the steam and oil Ways comparatively straight that all swirling or gyratory motion of the steam is eliminated, thus tending to uniformity of steam delivery through the burner nozzle. rllhe oil supply may be regulated independently of the steam supply, and the latter supply may be quickly regulated by means ot the eccentric rod mecha. nism hereinbefore described.

Having described my invention What l claim as new and desire to secure by Letters Patentis 1. A hydrocarbon burner, comprising a base member having a steam-Way opening therethrough, a nozzle formed on the upper end thereof, a support mounted in said nozzle and extending therethrough, an inverted cup-shaped plate mounted on said support, an oil-Way formed in said base member and terminating in the upper end thereof adjacent the steam nozzle in a discharge orifice, said oil-Way surrounding said steam-Way, a cup-shaped chamber formed on the upper end ot said oil-Way adjacent said discharge oriiice, said cupeshaped chamber forming With the inverted cup-shaped plate a mixing chamber, and means to regulate the size of the opening in the steam nozzle.

2. A hydrocarbon burner having a steam nozzle With an opening theretlnough, an oil nozzle incasing said steam nozzle and also having' an opening in alinement with said iirst opening, said oil nozzle being et conical form on its interior and tapering toward said second opening, a fixed stud passing upwardly -trom the interior ot said steam nozzle, a mixing plate carri-ed thereby, a sleeve sliding on said stud adapted to close said iirst opening, and means for actuating said sleeve.

3. A hydrocarbon burner comprising a steam nozzle oif substantially conical term and having an opening at its tip, an oil nozzle of substantially conical form incasing said steam nozzle, said oil nozzle having an opening in alinement with said iirst opening, a movable member mounted in said first opening for regulating the tioiv ot steam therethrough and a mixing plate beyond the said second opening, said oil-nozzle having an extension cooperating with said mixing plate to form a mixing chamber.

ln Witness that l claim the foregoing l have hereunto subscribed my naine this 29th day of March, 1909.
